l Claim.

My invention relates to improvements in brushes and has for one of the primary objects thereof the provision of a brush having a head so constructed and arranged whereby the rows of bristles may be readily cleaned when desired and with said head equipped with means operable to maximize accessibility of the bristles.

Another object of my invention is to provide a brush of the above described character which is simple in construction, `durable in use, eicient in operation and economical in manufacture.

Other objects and advantages will be apparent from the following description, appended claim and annexed drawing.

Referring to the drawing wherein like reference characters designate like parts throughout the several views:

Figure l is a bottom plan tion.

Figure 2 is a disassembled bottom plan view of the brush head.

Figure 3 is a side elevation of the brush,

Figure 4 is a -sectional View taken on the line 4-4 of Figure 2.

Figure 5 is a detail top plan view of the bridge.

1n practicing my invention, I provide a brush 5 formed with a handle 6 and a brush head 1 integrally connected together. In the form illustrated in the drawing, the brush is of the hairbrush type and the head, 1 comprises main and auxiliary sections 8 and 9 respectively detachable with respect to each other for a purpose hereinafter set forth.

The head 1 is of a transverse plano-cylindrical contour defining plane and convex faces I and I I respectively. The convex face of the main section 8 is formed with spaced longitudinally extending channels I 2 defined by lateral and interjacent ribs or adjutments I3 and I4 respectively. The side faces I of the interjacent rib I4 are planes and delineate a substantially dovetail configuration.

The auxiliary section 9 is fashioned with longitudinally extending tongues I6 integrally connected together at one end in spaced relation by the end of the main sechandle and with the tongues I6 disposed in saidchannels between the ribs. The tongues are of the same transverse contours as the contours of the channels and have their side faces disposed in appressed relation with the side faces of the ribs defining said channels whereby to frictionally secure the sections together in assembled condition. Obviously, the dovetail configuration of the rib I4 serves to view of my inven- .preclude the assembling or dismantling of the sections other than in an endwise direction.

The tongues and ribs are provided with longitudinal rows of bristles I8 and I9 respectively 940, Serial No. 326,750

with those of the tongues alternately arranged with respect to those of the ribs when the sections are in assembled condition whereby upon detachment of the sections suflicient space is provided to facilitate a thorough cleaning of the bristles between the rows of the respective sections.

As illustrated in Figure 5 of the drawing, the plane face of the bridge is provided with a transverseslot 20 whereby the fingernail of the user may be inserted therein to facilitate removal of the section 9 from the section 8. From the foregoing it will Ibe apparent that my invention is constructed in a manner whereby the sections may be readily molded from a suitable plastic material, for instance, Bakelite, or otherwise fabricated if desired.

Without further elaboration, the foregoing will so fully explain the invention that'others may, by applying -current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and sub-combinations.

It is obvious that the invention is not confined to the herein described use therefor as it may be utilized for any purpose to which it is adaptable. It is therefore to .be distinctly understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles of operation, which are capable of extended application in various forms, and that the invention comprehends all construction within the scope of the appended claim.

Having thus described my invention, I claim:

A brush head formed with an under substantially convex face and having an endwise removable section formed with spaced tongues, said head provided with longitudinal rows of bristles extending outwardly from said convex face and with alternate rows fixed to said tongues for removal from between the other rows to maximize cleaning accessibility of the respective rows, said convex face fashioned with coextending longitudinal channels accommodating said tongues and with the opposed Walls deiining each channel being disposed in appressed relation with the side faces of the tongue accommodated therein to frctionally maintain said tongues within said channels against accidental endwise displacement, said opposed walls defining each channel being disposed in parallelism and converging inwardly towards the opposed walls defining the adjacent channel forming a dovetail permitting only endwise movement of said section to effect detachment from said head.

ELBERT BRIGHTON.
